Retrospective audit for quality assessment of root fillings performed by undergraduate dental students in clinics.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objectives: To evaluate the technical quality of root canal obturations performed by undergraduate students. Methods: The records of 347 patients who underwent endodontic treatment by undergraduate students of Qassim University between 2018 and 2020 were assessed using standardised criteria based on obturation length, density and taper. All teeth that received primary endodontic treatment and had post-obturation periapical radiographs depicting the entire radicular length and the 2-3-mm periradicular area were included in the study. Results: A total of 653 canals of 397 teeth were evaluated. The maxillary central incisor was the most commonly assessed tooth (15.1%). Overall, 80.2% of the evaluated canals were deemed acceptable based on all three assessment criteria. Maxillary teeth had significantly better obturation quality than the mandibular teeth. The mesio-lingual canal had the lowest quality in all three criteria. Conclusions: The technical quality of root canal obturations performed by undergraduate students in Qassim University was acceptable in the majority of the evaluated cases. Among the evaluated parameters of obturation quality, length control was the most frequently observed deficiency. Additional measures are therefore required to improve the quality of the obturation length.
